Pathology

The pathology involving the CNS arises from
injuries, vascular insufficiency, tumors,
infections and disorders from other diseases.
Neurological medical problems are due to
interference with normal functioning of the
affected cells
Nervous System
Anatomy and Physiology
Review





The nervous system acts as a coordinated
unit both structurally and functionally
Communication network responsible for
coordinating and organizing the functions of
all body parts
The body’s link to the environment
Works with the endocrine system to maintain
homeostasis
Reacts in a split second
Functions



1.Regulates system
2. Controls communication
3. Coordinates Activities of body system
Divisions


Central nervous system ( CNS) : brain and
spinal cord –interprets incoming sensory
information and sends out instruction based on
past experiences
Peripheral nervous system ( PNS) : Cranial
and spinal nerves extending out from brain and
spinal cord---carry impulses to and from brain
and spinal cord
Neurological Terms







Anesthesia- complete loss of sensation
Aphasia-loss of ability to use language
Auditory/receptive aphasia- loss of ability to
understand
Expressive aphasia- loss of ability to use spoken or
written word
Ataxia- uncoordinated movements
Coma- state of profound unconsciousness
Convulsion- involuntary contractions and relaxation of
muscles
Neurological terms





Delirium- mental state characterized by
restlessness and disorientation
Diplopia- double vision
Dyskeinesia- difficulty in voluntary movement
Flaccidd- without tone- limp
Neuralgia- intermittent, intense pain, along the
course of a nerve
Neurological terms





Neuritis- inflammation of a nerve or nerves
Nystagmus- involuntary, rapid movements of
the eyeball
Paresthesia- abnormal sensation without
obvious cause, with numbness and tingling
Stupor- state of impaired consciousness with
brief response only to vigorous and repeated
stimulation
Vertigo- dizziness
Preparing a patient for a diagnostic
test






Answer question that the
patient may need clarification
Diet orders –NPO???

for test
An informed patient will be
more cooperative
Nursing assessment

cks
Know level education to
develop an individualized
teaching plan
Determine awareness of
actual or potential medical
diagnosis
Determine previous
experence with Dx test
Diagnostic test/ methods
A. Computerized Tomography- CT or CAT scan
computer analysis of tissues as x-rays pass
through them; has replaced many of the usual
tests: no special preparation or care after test
CT scan

B. lumbar puncture- spinal tap
–
–
–
–
Done under local anesthesia a puncture is made at
the junction of the third and fourth lumbar vertebrae
to obtain a specimen of cerebrospinal fluid (CSF)
CSF pressure measured

Spinal Cord Impairment

The vertebral column houses the spinal cord.
A small cartilage disk acts as a cushion
between the vertebrae. All sensory and motor
nerves to the neck, trunk, and extremities
branch out from the spinal cord. The degree of
disability and patient problems is related the
part of the body controlled by the injured or
disease nerves
Spinal Cord Injuries



Trauma to spinal cord may cause complete or
partial severing of the spinal cord
If severing is complete there is permanent
paralysis of body parts below site of injury
When there is partial damage edema may
cause a temporary paralysis
